How to Identify Real Silk？

There are many methods for testing real silk, such as using touch, the sound of friction, and the fabric's organizational pattern. These methods require highly specialized individuals to accurately identify the authenticity of silk. For non-professionals, we recommend using the burn test.

     This is not a standard test performed on silk! However, it is a fairly definitive test.

        Extracted from the fabric edge off a bunch of silk yarn, lit with a match. The bunch of Silk burn slowly with faint glow. Firstly, it will curl into a ball with a similar smell of burning human hair or bird hair.   

        Then, after burning into the dark brown globular, once you touch the globular,it will be broken into powder. Finally, when leaving the flame, it stops burning immediately. So Silk is also a natural flame retardant.

       The burning silk should smell like burning hair. (Both substancesv mainly consist of a fibrous protein–fibroin in the case of silk and keratin in the case of hair.)

        A synthetic fabric will burn with a smell like burning plastic and will drip, form a black ball of residue (not ash), and produce black smoke. It will continue to burn even after the flame is taken away.

       TTENTION PLEASE! The reaction of the burn test on silk thread is very similar to the reaction of the same test with wool yarn. Make sure that there is a bucket of water closing by. Some fabrics that look like silk are actually extremely flammable and will need to be doused immediately.
